Abstract

Multiphoton dissociation of dichlorofluoromethane induced by the incoherent superposition of two pulsed infrared laser beams tuned at 927 and 1086 cm^-1 is reported. The experiments were carried out either simultaneously or with a given time delay between both beams in the 1 - 3 J cm^-2 fluence interval, and neat gas pressure in the static cell raging between 0.4 and 2 mbar. Simultaneous and delayed two frequency multiphoton spectra of CF₂Cl₂ are obtained. Some spectroscopic structure in the quasicontinuum is detected and the dependence of the bimodal irradiation dissociation yield on time delay is explained.
